Our verdict on Aurelius Finance
Aurelius Finance suits crypto holders who want to borrow a stablecoin against collateral on Mantle and are comfortable with DeFi contract risk. Its main strength is the reported interest-free aUSD loan, along with a route through OKX Wallet. The main caveat is that fees, collateral rules, liquidation terms and audits are not clearly published, so the true cost and risk are hard to judge before you borrow. Start with a small position and read the app's terms closely.

What is Aurelius Finance?
Aurelius Finance is a decentralized finance protocol on Mantle that lets users deposit collateral and borrow aUSD, its native stablecoin. Sources describe the product as a lending and collateralized-debt platform, and one third-party summary says aUSD loans are interest-free. The protocol is also integrated into the OKX Wallet, which gives its users a route into the lending and borrowing features. The name Aurelius Finance is also used by unrelated businesses, including a family office and a UK private equity investor, and those are not part of this protocol.
How Aurelius Finance works
Aurelius Finance works like other collateralized lending markets. A user deposits crypto assets as collateral into a smart contract on Mantle. The contract then allows the user to borrow aUSD, the protocol's native stablecoin, up to a limit set by the value of that collateral.
Because the debt is overcollateralized, the deposit is worth more than the loan. If the collateral falls too far in value, the position can be liquidated to protect the stablecoin. Repaying the aUSD debt releases the collateral. Third-party summaries describe the loans as interest-free, which is an unusual feature, and the cost of borrowing is one of the details to confirm in the app.

Pros and cons
What we like
- Third-party summaries describe aUSD loans as interest-free
- Available through an OKX Wallet integration
- Operates on Mantle, an Ethereum layer-2 network
- Clear basic model: deposit collateral, borrow a stablecoin
Watch out for
- Full fee schedule and borrowing costs are not published
- Collateral types, loan-to-value limits and liquidation rules are not published
- aUSD is an overcollateralized stablecoin, so a sharp fall in collateral value can put its peg under pressure
- Audit status is not established, which makes smart-contract risk hard to size
- Independent coverage is thin and the name is shared with unrelated firms
Aurelius Finance fees
Aurelius does not publish a full fee schedule in the material available for this review. Third-party write-ups describe aUSD loans as interest-free, with a borrowing cost mentioned but not quantified.
Before borrowing, check the app for any origination, stability or liquidation charges and how they are calculated. Network gas fees on Mantle are paid separately to the network.
Is Aurelius Finance safe?
Aurelius does not publish a full audit history in the material available for this review, so smart-contract risk cannot be sized from public information. Using the protocol means trusting its contracts and the price feeds and collateral rules they depend on. Funds are not held by a company custodian in the way an exchange holds them, but a contract failure or exploit could still cause losses.
The OKX Wallet integration provides access to the lending features and does not change the underlying contract risk. Regulatory status for the protocol is not stated in the sources reviewed. Online financial and borrowing products carry real risk of loss, so check that such services are legal where you live.

Does Aurelius Finance charge interest on aUSD loans?

Check the app for any origination, stability or liquidation charges before borrowing. Aurelius does not publish a complete fee schedule in the material available for this review.
What are the risks of borrowing aUSD?
